A client who had a knee replacement surgery receives a prescription for enoxaparin 30 mg subcutaneously every 12 hours for 10 days. The medication is available in 30 mg per 0.3 mL prefilled syringes. How many mL should the practical nurse (PN) administer each day? (Enter numerical value only.)
The Correct Answer is ["0.6"]
- Medication dose: 30 mg enoxaparin
- Medication concentration: 30 mg per 0.3 mL (prefilled syringe)
- Frequency: Every 12 hours
- Duration: 10 days
Calculation:
- Injections per day: Since the medication is given every 12 hours, the client will receive injections 2 times per day (24 hours / 12 hours/injection).
- Total medication per day: To find the total amount of enoxaparin needed per day, multiply the single injection dose by the number of injections:
Total enoxaparin/day = Dose per injection x Number of injections/day = 30 mg/injection x 2 injections/day = 60 mg/day
- Volume of medication per day: Now, we need to find the volume of solution needed to deliver the total daily dose (60 mg) based on the medication concentration (30 mg/0.3 mL). We can achieve this with a proportion:
Volume (mL) / Total dose (mg) = Concentration (mg/mL)
Volume (mL) = (Total dose (mg) x Concentration (mL/mg)) / Concentration (mg/mL)
Plugging in the values:
Volume (mL) = (60 mg x 0.3 mL/mg) / 30 mg/mL
Volume (mL) = 18 mL / 30 mL/mL
Simplifying:
Volume (mL) = 0.6 mL
Therefore, the practical nurse (PN) should administer 0.6 mL of enoxaparin each day.

Correct Answer is A
Explanation
A. The upper torso is where the center of gravity shifts in elderly adults. As people age, their center of gravity moves higher due to changes in body composition and muscle strength, which can affect balance.
B. The feet are the base of support, not the center of gravity. The center of gravity is located higher up in the body.
C. The upper extremities do not represent the center of gravity. The shift in the center of gravity affects overall balance and stability.
D. The head does not represent the center of gravity; it is primarily located in the upper torso. The head's position influences balance but is not the center of gravity.
Correct Answer is B
Explanation
A. The client's contractions are not regular or intense enough to indicate active labor, so immediate hospital admission is not necessary.
B. Instructing the client to call the clinic when her contractions occur 5 minutes apart for one hour ensures she is monitored for the progression of labor and can seek timely assistance when labor becomes more active.
C. While a urinary tract infection could cause contractions, the primary focus should be on monitoring labor progression, not diagnosing a UTI at this stage.
D. Hydration is important, but the primary instruction should relate to monitoring contraction patterns for signs of active labor.
